Reciprocating motion is the up and down motion.. This motion is converted into ratational motion by the crankshaft.. This because it (crankshaft) is frequently combined with flywheel thus to keep the discontinous reciprocating energy as rotation energy..
Added points.
Crankshaft drive is the entire mechanism that converts the engine's piston up and down motion where as in cylinder a piston is moved as aresult of applied fluid pressure, the actuator provide rotary motion
(Lawrence dinala- Law Dinh)
It is the reciprocating motion of the pistons that is changed into rotary motion by the cam axle.
Rotary means going around, like in a Wankel. Reciprocating means going back and forth. like in a ordinary piston engine.
As the reciprocating pump operates though the reciprocation of the follower,it guides the suction and the compression of water in the pipe.That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which deliver it to the reciprocating pump, the suction and discharge takes place.
The reciprocating motion of the pistons is converted into rotary motion which is connected to a shaft connected to an electrical generator .

In very crude terms, rotary motion is round & round, reciprocating motion is back & forth. A piston engine has both kinds of motion. The crankshaft displays rotary motion, the pistons display reciprocating motion. The camshaft displays rotary motion, the valves display reciprocating motion. Out on the suspension, the wheels display rotary motion and the shock absorbers display reciprocating motion. (One might say the shocks don't display "true" reciprocating motion because they're not CONSTANTLY in motion, but that one drives on better roads than they have here!)

The crankshaft and connecting rod (or piston rod).
The four types of motion mechanisms are rotary motion, linear motion, oscillating motion, and reciprocating motion. Rotary motion involves circular movement, linear motion involves movement in a straight line, oscillating motion involves back and forth movement, and reciprocating motion involves alternating movement in opposite directions.
Crankshaft transfers a reciprocating motion into a rotary motion into transmission which makes vehicle move.
Scotch Yoke Mechanism is a mechanism in which the rotary motion is converted to reciprocating motion, with a single link or bar. The reciprocating system has to be constrained along the guide ways for linear motion.
Rotary means going around, like in a Wankel. Reciprocating means going back and forth. like in a ordinary piston engine.
Two types of system I can think of:A cam mounted on a rotating shaft can push against a rod. If the rod is held against the cam by a spring then the system is capable of reciprocating action.A crank: The crank attached to the pedals on a bicycle is an example, although it converts reciprocating motion to rotary motion.
connecting rod is provided between crank and the piston,which converts the reciprocating motion of the piston into rotary motion of the crank.
